Defect‐Free Transfer Principles for Scalable, Thin Garnet‐Based Hybrid Solid Electrolytes in Solid‐State Batteries

Advanced Functional Materials, EarlyView.
Defect‐free transfer principles enable scalable fabrication of 15 µm‐thin garnet‐based hybrid solid electrolytes. Hansen solubility parameters correlate interfacial compatibility with coating, transfer, and impregnation behavior, guiding rational selection of slurry/substrate, binder/substrate, and binder/polymer electrolyte combinations.
